[VBox-users] VbglR3Init failure

[Roger H. <ro...@mo...>]

I recently upgraded VirtualBox to version 7.0.10 and it is run on a 
Windows 10 host to provide Devuan Linux guest machines.

I also upgraded the Devuan version from chimaera to daedalus which 
upgrades the Linux kernel from 5.10 to 6.1 -- the upgrade proceeded without 
any problems with Virtual Box Guest Additions installed from the virtual 
optical drive. Attempting to start X11 graphics causes the system to hang, 
and the error is presumably

        VbglR3Init failed with rc=VERR_FILE_NOT_FOUND

from the vboxadd-install.log; when the virtual machine is started using 
Linux kernel 5.10 (for which the modules were recompiled) there is no 
problem.

The question is how to fine the missing file; what is it?
